Ring Enhancement

A CT finding in the brain consisting of a radiolucent zone surrounded by a faint radiodense rim, in turn surrounded by a 2nd radiolucent zone outside of the rim, where the rings correspond to regional oedema, hypervascularity and hypercellularity with early ingrowth of fibroblasts. Ring enhancement is a nonspecific finding typically linked to early cerebral abscesses
DiffDx Infections—pyogenic abscess, toxoplasmosis, cysticercosis, necrotising fungal lesions; neoplasms—brain tumours—e.g., aggressive glial tumours, cystic astrocytoma, primary brain lymphoma, metastases with central necrosis; demyelinating disease; vascular lesions—resolving infarction, hematoma, thrombosed giant aneurysm; radiation therapy; postoperative changes; IV contrast material may be used to enhance faint radiodense ‘rings’
